Description

Granite fiber crops stone water-bath type dust-removing desulfurizing device

Technical field

The utility model belongs to a kind of boiler exhaust gas desulphurization plant, particularly a kind of granite fiber crops stone water-bath type dust-removing desulfurizing device.

Background technology

In the boiler in the coal burning process in the combustion gas harmful substance mainly contain flue dust, sulfur dioxide, oxynitrides etc., sulfur dioxide, oxynitrides can produce acid rain and destroy environment, polycyclic aromatic hydrocarbon, BaP are carcinogenic substances, and flue dust all has harm to building, animal, plant; And the boiler exhaust gas devulcanizer has following several form at present: in the majority with the combined type desulfurizing dust-collector, the combined type desulfurizing dust-collector has two kinds of forms of dry type and wet type, and dry type composite desulfate deduster is simple in structure, has problems such as efficient is lower, fluctuation of service; Wet type composite desulfate deduster, industry or the most wet method sulphur removing and dust removing technology that adopt of heating boiler based on fire coal, promptly the chemical reaction that is undertaken by alkaline solution and sulfur dioxide reaches the desulfurization purpose, the desulfuration efficiency height, but there are problems such as band water and stifled ash, when flue gas passes through the pond, can take a part of water out of, and not have de-watering apparatus, when aqueous vapor is passed through air-introduced machine, can produce corrosion to air-introduced machine, wet type desulfurizing dust collector has certain desulfurization and dedusting effect, but its structure is complicated, and floor space is many, cost of manufacture is higher, promotes the use of thereby influenced.The devulcanizer that the types such as fountain, water film type and water-bath type of monomer are also arranged in addition, the band water of this class devulcanizer various degrees, desulfurization instability and the big shortcoming of flue gas resistance.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective, and a kind of granite fiber crops stone water-bath type dust-removing desulfurizing device is provided, and it is little to have floor space, reliable, and long service life improves desulfuration efficiency and service behaviour, simplified apparatus, the characteristics of reduction cost.

The utility model is achieved through the following technical solutions: a kind of granite fiber crops stone water-bath type dust-removing desulfurizing device, it is characterized in that: it comprises the devulcanizer housing, the devulcanizer housing is fixed on the top in pond, the devulcanizer enclosure interior is provided with three road partition walls, the devulcanizer enclosure interior is divided into the clean room successively, the flue-gas dust-removing and desulfurization chamber, secondary pulse chamber and dewatering station, the devulcanizer housing is respectively equipped with gas approach that is positioned at top, flue-gas dust-removing and desulfurization chamber and the exhanst gas outlet that is positioned at the dewatering station top, wherein be respectively equipped with first passage and second channel between gas approach and sweet gas housing two side, first partition wall bottom is for widening partition wall, form narrow crack with the water surface in the pond, second partition wall bottom stretches in the water surface of pond, the 3rd partition wall bottom then is higher than the pond water surface, be staggered in the dewatering station several layers of dividing plate are installed, at first passage, second channel and porch, clean room are separately installed with spray equipment.

Above-mentioned devulcanizer housing adopts granite fiber crops barnacle system.

The utlity model has following advantage: 1, the dust-removal and desulfurizing water is stored in the pond, externally remains static substantially, and not outwards discharging is convenient to carry out the cohesion of ash in the pond substantially, uses the Machine for cleaning-out ash ash disposal, and water quality focuses on, non-secondary pollution; 2, add the alkali lye desulfurization, efficient is up to 85-90%; 3, adopt the atomizing of recirculated water spray, water consumption is minimum, and operating cost is low; 4, the devulcanizer housing adopts granite fiber crops barnacle to build, and is wear-resistant, corrosion-resistant, short construction period; 5, do not need to establish sedimentation basin in addition, do not have workbench, simple in structure, floor space is little.

The specific embodiment

Embodiment: a kind of granite fiber crops stone water-bath type dust-removing desulfurizing device, it is the top that the rectangle devulcanizer housing 1 of granite fiber crops barnacle system is fixed on pond 2, devulcanizer housing 1 inside is provided with three road partition wall 3-1,3-2,3-3, devulcanizer housing 1 inside is divided into clean room 4 successively, flue-gas dust-removing and desulfurization chamber 5, secondary pulse chamber 6 and dewatering station 7, devulcanizer housing 1 is respectively equipped with gas approach 8 that is positioned at 5 tops, flue-gas dust-removing and desulfurization chamber and the exhanst gas outlet 9 that is positioned at dewatering station 7 tops, wherein be respectively equipped with path 10 between gas approach 8 and devulcanizer housing 1 two side, the first partition wall 3-1 widens partition wall for taper in the bottom, form narrow crack with the water surface in the pond 2, second partition wall 3-2 bottom stretches in 1 water surface of pond, the 3rd partition wall 3-3 bottom then is higher than pond 1 water surface, be staggered in the dewatering station 7 two layers of dividing plate 11 are installed, spray equipment 12 is installed respectively at

path

10 and 4 porch, clean room.

Operation principle: dust-laden, sulfur-containing smoke gas are under the air-introduced machine suction function, enter gas approach, through the alkali lye atomizing that the spray equipment of first passage sprays ejaculation for the first time mix, after the washing, in bottom cone reducing place, with the high speed impact water surface, carry out disturbance with water in the pond, make that flue gas and water are full and uniform to be contacted, at this moment most of dust granules desulfurization product falls into the pond, finishes dust-removal and desulfurizing first; When flue gas climbs over the first partition wall bottom cone, change traffic direction, from widen the narrow crack between the partition wall bottom and the water surface, skim over the water surface with quite high speed, flue gas impacts and skims over the water surface and all will evoke water droplet and vibration, play dedusting and desulfidation once more, after flue gas changes traffic direction, enter the clean room, second group of spray equipment spray in the porch, again flue gas is carried out the primary atomization washing, flue gas after being purified is through first passage, second channel enters the secondary pulse chamber, flue gas once more with the pond in water impact, further purified flue gas, last flue gas enters dewatering station, after purifying once more by several layers of staggered dividing plate behind the fume-dehydrating, discharges chimney by air-introduced machine and enters atmosphere, reach 85-90% dust-removal and desulfurizing efficient, be higher than new environmental protection standard DB12/151-2003II.
